>> Of course, the US shouldn't be surprised if China deprives Apple of an ingress route into the Chinese economy by banning the sale of iPhones there. After all, that is what the US did to China in 2017. <<
We already have some insights from how China kicked out South Korean businesses one by one: Samsung was forced out about a decade ago. In response, the conglomerate pulled out of China and closed the last smartphone factory in 2019; and left for Vietnam. Samsung is still #1 in global smartphone sales without any Chinese sales and the company's output accounts for as much as 20% of Vietnam's GDP today. The same can be said for Hyundai/Kia who was once among the top sellers in China in early 2010's , but now with a diminutive market share. They rose from #5 to #3 in global auto sales during the same time. China also blocked and harrassed South Korean EV battery businesses from doing business in China starting mid 2010's, now with almost nada market share; now they are expected to dominate 80+% of the NA market and 70+% of global market share.
Nobody is surprised at the CCP's quest for dominance and the US is taking appropriate actions, such as the IRA/CHIPS Act/Huawei ban/etc to counter China's aggression. Apple will continue to do well without China even if they are forced out. There is a lot of opportunity outside China.
>> Huawei became a behemoth in smartphone terms without access to one of the world's biggest smartphone markets. <<
Huawei's smartphones were never competitive. Their phones were available for sale in the US as early as 2013, but sold piss-poor in the US with less than 0.10% market share -- Huawei can't sell jack without demand driven by nationalism.
>> ... How would Apple do without access to China. ... That particular card hasn't been played by China yet. <<
No worries. As explained above,
Apple has already begun the process of moving out of China.
>> These results seem to show a turnaround with revenues slightly up in spite of US efforts to destroy the company and huge R&D investments. <<
